CBT3251 1-of-8 FET multiplexer/demultiplexer Rev. 4 — 24 March 2021 Product data sheet 1. General description The CBT3251 is a single-pole, 8-throw bus switch. The device features an output enable input (OE) and three select inputs (S0, S1 and S2). When OE is LOW the switch is enabled and the select inputs can be used to connect the A terminal to one of the eight B terminals. 2. Features and benefits • • • • • • • • 5 Ω switch connection between two ports Direct interface with TTL levels Overvoltage tolerant control inputs to 5.5 V IOFF circuitry provides partial Power-down mode operation Minimal propagation delay through the switch Latch-up protection exceeds 100 mA per JEDEC standard JESD78 class II level A ESD protection: • HBM JESD22-A114E exceeds 2000 V • MM JESD22-A115-A exceeds 200 V • CDM JESD22-C101C exceeds 1000 V Specified from -40 °C to +85 °C 3.

This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. Measured by the voltage drop between the A and the Bn terminals at the indicated current through the switch. The lowest voltage of the two (A or Bn) terminals determines the ON resistance. Typical value is measured at VCC = 4 V; Tamb = 25 °C. CBT3251 Product data sheet All information provided in this document is subject to legal disclaimers.
